Aviation accident data has limitations for establishing airport safety zones used to guide airport-vicinity land use decisions. Establishing uniform reporting criteria across responsible agencies will assist local jurisdictions to define safety zones and apply them to maintain airport viability.
Vegetation and grass height is suggested to be between 7-14 inches on airports to deter small bird species; this concept has been tested in the past, with mixed results. I suggest a study should be conducted building on the previous publications keeping in mind new technologies and different grass management strategies to determine if current best management strategies are sufficient or may need to be updated.
Research is recommended to see how to better capture benefits stemming from proposed projects when conducting BCAs for GA airports.
